None of my business...but I have to ask...just why anyone would want a system/Windows partition to be larger than is really necessary?
Doing such...imperils everything on that partition if you develop problems...and we all know that there will be problems
, sooner or later...where the partition may become damaged, the hard drive becomes problematical, Windows becomes damaged, or malware intrudes.
Not to mention the trouble that a user would have running malware scans, chkdsk /r, or defragging.
Smaller is better if one wants to minimize potential losses, IMO.
